Abstract

Cycloheptimidazolinium halides of the general formula <FORM:1110725/C2/1> wherein R represents hydrogen, a phenyl group, a halogen atom or an alkyl group having from 1 to 5 carbon atoms; R1 and R2 may be the same or different and represent an alkyl group having from 1 to 5 carbon atoms, a phenyl group, a substituted phenyl group, an aralkyl group or a substituted aralkyl group; and X represents a halogen atom are prepared by reaction of a troponeimine derivative of the formula <FORM:1110725/C2/2> with a halogeno-formic acid ester of the formula XCOOR3, wherein R3 represents an alkyl group having from 1 to 5 carbon atoms.
